Description

Technical Field

[0001] This utility model relates to the field of chemical reactor structure technology, and in particular to a feeding auxiliary device and a reactor. Background Technology

[0002] In chemical production processes, reaction vessels are generally used as containers for chemical reactions. These vessels are equipped with feed pipes and inlets for material entry. The feed pipes typically accept liquid materials, while the inlets can accept both solid and liquid materials. In actual production, some highly viscous liquid materials also need to enter through the feed pipes. To improve feeding efficiency and ensure the material enters at a higher speed, a propulsion device is usually connected to the feed pipe. This device includes a conveying pipe connected to the feed pipe, a screw conveyor inside the conveying pipe, and a drive motor at the end of the conveying pipe away from the feed pipe to rotate the screw. An inlet pipe is also installed on the conveying pipe to guide highly viscous materials into the conveying pipe, where they then follow the screw to the feed pipe for feeding. However, in actual operation, if the screw speed is too high, the material may not be able to enter the conveying pipe smoothly, thus limiting further improvements in feeding efficiency. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a feeding auxiliary device that solves the problem that excessively high screw speeds limit the improvement of feeding efficiency.

[0004] According to an embodiment, a feeding auxiliary device is provided, comprising a horizontally arranged conveying pipe, a drive motor at one end of the conveying pipe, and a feeding pipe at the other end. A mounting shaft is coaxially arranged inside the conveying pipe, with one end extending rotatably out of the conveying pipe and connected to the shaft of the drive motor. A first variable-diameter spiral and a constant-diameter spiral are fixedly connected to the mounting shaft. The first variable-diameter spiral is close to the drive motor and its diameter gradually increases until it connects with the constant-diameter spiral. An inlet pipe, communicating with and close to the variable-diameter spiral, is also fixedly connected to the conveying pipe. This solution provides a first variable-diameter spiral inside the conveying pipe. High-viscosity materials are introduced to the first variable-diameter spiral through the inlet pipe. Because there is space between the first variable-diameter spiral and the conveying pipe, the material can enter more smoothly and then be propelled into the feeding pipe as the first variable-diameter spiral and the constant-diameter spiral rotate. Compared to existing technologies, the rotation speed of the first variable-diameter spiral and the constant-diameter spiral can be higher, thus improving feeding efficiency within a certain range and solving the problem that excessively high spiral speeds in existing technologies limit the improvement of feeding efficiency.

[0005] Furthermore, the inlet tube is located above the delivery tube.

[0006] Furthermore, a second variable diameter screw is fixedly connected to the mounting shaft. The second variable diameter screw is connected to the equal diameter screw and its diameter gradually decreases and extends into the feed pipe.

[0007] Furthermore, the conveying pipe includes a first pipe section and a second pipe section. The drive motor and the inlet pipe are connected to the first pipe section, and the second pipe section is connected to the feed pipe. The first pipe section and the second pipe section are respectively fixedly connected with a first connecting ring, and the two first connecting rings are detachably connected.

[0008] Furthermore, the second pipe section and the feed pipe are respectively fixedly connected with second connecting rings, and the two second connecting rings and the two first connecting rings are connected by multiple long bolts.

[0009] Furthermore, the equal diameter spiral is located inside the second pipe section, and the second variable diameter spiral extends from the second pipe section into the feed pipe.

[0010] According to an embodiment, a reaction vessel is also provided, which includes the above-described feeding auxiliary device.

[0011] Compared with the prior art, the present invention has the following beneficial effects: A first variable-diameter spiral and a constant-diameter spiral are connected inside the conveying pipe to propel the material. There is space between the first variable-diameter spiral and the conveying pipe, so the material can enter more smoothly. Then, as the first variable-diameter spiral and the constant-diameter spiral rotate, they are pushed into the feed pipe. Compared with the prior art, the rotation speed of the first variable-diameter spiral and the constant-diameter spiral can be higher, so the feeding efficiency can be improved within a certain range. This solves the problem that the excessively high spiral speed in the prior art will limit the improvement of feeding efficiency. Attached Figure Description

[0013] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0014] like Figure 1 , 2As shown, this embodiment provides a reactor. A feed pipe 2 is provided at the upper end of the reactor 1. A feeding auxiliary device is also provided at the feed pipe 2. The feeding auxiliary device includes a horizontally arranged conveying pipe and a drive motor 3. Unlike the prior art, the conveying pipe in this solution adopts a segmented structure, that is, the conveying pipe includes a first pipe segment 4 connected to the drive motor 3 and a second pipe segment 5 connected to the feed pipe 2. An inlet pipe 6 is also connected to the first pipe segment 4. A mounting shaft 7 is coaxially arranged inside the conveying pipe. One end of the mounting shaft 7 extends rotatably to the outside of the conveying pipe (outside the end of the first pipe segment 4 away from the reactor 1) and is connected to the rotating shaft of the drive motor 3. A first variable diameter spiral 8 and a constant diameter spiral 9 are also fixedly connected to the mounting shaft 7. The first variable diameter spiral 8 approaches the drive motor 3 and its diameter gradually increases until it connects with the equal diameter spiral 9. The inlet pipe 6 is located above the first pipe section 4. During operation, materials with higher viscosity enter through the inlet pipe 6 and flow downwards. There is a space between the first variable diameter spiral 8 and the first pipe section 4 (similar to the prior art, the equal diameter spiral 9 slides in contact with the inner wall of the conveying pipe). Therefore, the material can fall more smoothly into this space and then be pushed towards the feed pipe 2 as the first variable diameter spiral 8 and the equal diameter spiral 9 rotate. Compared with the prior art, the rotation speed of the first variable diameter spiral 8 and the equal diameter spiral 9 (both rotate in the same direction) can be higher, thus improving the feeding efficiency within a certain range and solving the problem that the excessively fast spiral speed in the prior art would limit the improvement of feeding efficiency.

[0015] In further proposals, such as Figure 1 , 2 As shown, a second variable diameter spiral 10 is also fixedly connected to the mounting shaft 7. The second variable diameter spiral 10 is connected to the equal diameter spiral 9 and its diameter gradually decreases and extends into the feed pipe 2. The equal diameter spiral 9 is located in the second pipe section 5, and the second variable diameter spiral 10 extends from the second pipe section 5 into the feed pipe 2 (so that the entire device can be more easily removed from the feed pipe 2 during disassembly). In this way, the material can be directly pushed into the feed pipe 2. In another embodiment, the second variable diameter spiral 10 can also be set to extend into the reactor 1. In a further embodiment, the first pipe section 4 and the second pipe section 5 are respectively fixedly connected to the first connecting ring 11, and the second pipe section 5 and the feed pipe 2 are respectively fixedly connected to the second connecting ring 12. The two second connecting rings 12 and the two first connecting rings 11 are connected by multiple long bolts 13, which facilitates the disassembly of the conveying pipe and facilitates subsequent inspection and maintenance.

[0016] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
